The QR code-based shared charging pile system is an intelligent charging facility integrating Internet technology, Internet of Things (IoT) technology, and smart grid technology. It aims to provide convenient and efficient charging services for new energy transportation modes such as electric vehicles and electric bicycles. Below is an overview of the QR code-based shared charging pile system:
I. System Composition
The QR code-based shared charging pile system mainly consists of two major parts: hardware and software. The hardware components include the charging pile itself, circuit boards, display screens, communication modules (such as 4G communication modules), GPS positioning modules (equipped in some charging piles), and relays. The software components involve WeChat mini-programs or apps, backend management systems, and payment interfaces. These hardware and software components work together to realize functions such as QR code-based charging, remote monitoring, and intelligent scheduling.
II. Working Principle
Users scan the QR code on the charging pile with their mobile phones to access the mini-program or app interface. On the interface, they select the corresponding charging service and complete the payment verification. Upon receiving the successful payment signal, the charging pile controls the relay to close and begins supplying power to charge the electric vehicle. During the charging process, the charging pile monitors data such as battery level, voltage, and current in real-time and uploads it to the backend management system through the communication module. After charging is completed, users can remotely end the charging process through the mini-program or app, and the charging pile automatically cuts off the power and generates a charging details report.
III. Advantages and Characteristics
The QR code-based shared charging pile system is characterized by convenience, intelligence, and efficiency. Users do not need to carry specific charging cards or keys; they can complete the charging operation solely through their mobile phones. At the same time, the system can intelligently schedule charging times and power allocation based on grid load conditions and user charging needs, achieving efficient energy utilization. Additionally, the system is equipped with safety protection mechanisms such as overload protection and short-circuit protection to ensure the safety and reliability of the charging process.
The QR code-based shared charging pile system, with its convenience, intelligence, and efficiency, is gradually changing the landscape of electric vehicle charging and providing users with higher-quality charging services.
